BRICK LINTELS

STRETCHER COURSE BRICKWORK

Lintel consist of at least three courses of bricks bonded with mortar. The first course of bricks, each vertical joint, has anchors inserted. Between the first and the second horizontal seams, and betyween the second and the third courses of bricks there is a longitudinal rebar reinforcement Murfor RND/Z-50. The longitudinal rebar at horizontal joints shall go outside the edges of the opening at 250 mm and 500 mm at the corners of the building.

In this way lintels up to 2,00 m are mouinted. If bigger apertures need to be made the same way, bracket suspensions GSP or KP-M are used.

ATTENTION! The bricks of the first course should be full. HERE AND FURTHER. Seeking to reach the nominal strength making lintels during hot season, it is recommended to moistened them for 2 weeks.Mortar marking should be at least 100

LINTEL FROM LONG BRICK

THIN-LAYER DECORATION MASONRY LINTEL

ATTACHING SG/2 CONNECTIONS ON LONG BRICKS

Lintel mounting from long brick is analogous to the lintel mounting from standart brick with the addition of connections SG/2, estimating 1-2 connections for the brick at the first row.

ATTENTION! Before laying bricks the first row, the ends of the bricks shall be processed with primer (quarz based). It is necessary for a better mortar, brick and metal adhesion.

Mounting of narrow brick lintel is analogous to the mounting of lintel from standard brick by additionally reinforcing one masonry row. The number of reinforced lintel rows – at least 3 rows.

ATTENTION! Decorative masonry layer from bricks 50-65 mm is allowed at low-height construction, up to 2 floors.

At the back wall groo-ves are made (~5 mm wide, ~150 mm long, and ~15 mm depth)

SG/2 connections are introduced into the mortar

BRICK LINTELS

SOLDIER COURSE BRICKWORK

The most common type of laying brick lintels is soldier course brickwork. In this case the bricks can be both solid and hollow. Sometimes, to achieve a better effect, 2 first courses of brick laying above the opening are soldier courses.

BRICK LINTELS | ROWLOCK COURSE BRICKWORK

BRICK LINTELS

ROWLOCK COURSE BRICKWORK

Rowlock course brickwork is performed at a 90° angle to the façade because doing this it is possible to hide the heat insulation layer behind the decorative brickwork. Depending on the thicknes of this layer the bottom row of bricks can protrude from the façade plane – this way the lintel will be emphasized not only by pattern, but by relief too.

COMBINED BRICKWORK

COMBINED BRICKWORK WITH ONE AND A HALF BRICK

THIN DECORATION MASONRY LINTEL

A classical type of brick lintels by altering a full brick and two identical halves. The only important condition when selecting combined brickwork is dimen-sions of the bricks. Their ratio shall be 2:1, e.g. 250х120х65h. The lintel should start and finish with soldier course brickwork. The layout of the lintel is identi-cal to the lintel made in the vertical way.

Lintel mounting from thin bricks is analogous to lintel mounting from standard bricks with additional reinforcement of one brick row. The number of reinforced masonry rows of the lintel shall be at least 3 rows.

BRICK LINTELS ON BRACKETS

MASONRY ON THE BRACKETS REINFORCED BY MURFOR

THICKNESS OF THE HORIZONTAL JOINT

In case of large openings (>2 m), there is a risk of deflection as well as destruction of the lintel. In order to avoid this, suspended brackets GSP should be used. They are fixed to the carrying wall of the reinforced concrete lintel while the free end is inserted into the horizontal joint between the first and the second rows of brickwork. In this case, the load is transferred from decorative brickwork to the load-bearing structure through the brackets.

Quantity of suspended brackets and their arrangement above openings are calculated separately in every individual case.

Upon mounting of the reinforcement in the horizontal joint, its thickness should not exceed 10 mm and in case of using brackets it should not exceed 12 mm. When placing reinforcement, there should be no obvious changes in the thickness of the joint, and its application should not have any influence on the general appearance of the brickwork.

MOUNTING OF BRICK LINTELS OF OVER 2 M BY USING SUSPENDED BRACKETS GSP

Seam with brackets 12 – 15 mm

Seam with rebar and connections 10 – 12 mm

Thickness of a lowered joint with reinforcement and lintel hooks is 8 to 9 mm.
